TL;DR: The results indicate the existence of a differential lunar highland crust, probably feldspathic, related to the plagioclase-rich materials previously found in the samples from Apollo 11, Apollo 12, Apollo 14, Apollo 15, and Luna 16.

TL;DR: In this article, the free-atom Auger and Coster-Kronig energies have been calculated in a neutral-atom potential, and the results are consistently smaller, sometimes by a factor of 3, than expected from previous theory, and do not show the pronounced effect of predicted super-Coster Kronig transitions.

TL;DR: In this paper, a hole localization parameter and an energy parameter were derived from the Auger spectra of metals with both open and filled $3d$ bands, which can be used to quantitatively evaluate the contributions of hole-hole interaction and relaxation, to the total energy difference between single and double-hole final states.

TL;DR: X-ray photoelectron spectroscopic measurements of various valence states of Fe and Cu in several compounds using ion-sputtering reduction are presented, and the potential usefulness of this time-dependent and in situ method is discussed as discussed by the authors.

TL;DR: The lunar surface was mapped with respect to magnesium, aluminum, and silicon as aluminum/ silicon and magnesium/ silicon intensity ratios along the projected ground tracks swept out by the orbiting Apollo 16 spacecraft to confirm the idea that the moon has a widespread differentiated crust (the highlands).
